"Heavy showers, which will most likely become thundery in places, are expected to develop quite widely across parts of England and Wales later Friday morning and through the afternoon. "Some of the showers are likely to become focussed into slow-moving bands, particularly over south west England, with some locations receiving around 20mm in an hour.

"As is the nature of showers however, many places within the warning area will miss them altogether, and have a dry day."
